The closed minded tends to be a nuisance in  a rational discussion and low mentality, make their presence everywhere to fulfill the insecurity in them just because they don't like it. These are shameless people who will not grow up and a burden to the society, while the others continue to make progress in science and contribute towards a civilized living environment.

Usually these people stick to their own kind but others are intrusive and feel ire when others is smarter and talented then them, continue to make a fool of their own kind but then it does fuel the ratings in this forum.
